PATENT FILLING-CARRIER FOR LOOM-SHUTTLES.

S?ECIFICATEON forming part of Letters Patent No. 682,534, dated September 10, 1901.

Application filed March 28, 1901. Serial No. 53,305. (F0 model.)

To ctZZ whom it may concern.-

Be it known that I, GEORGE O. DRAPER, a citizen of the United States, and a resident of Hopeda-le, county of Worcester, State of Massachusetts, have invented an Improvement in Filling-Carriers for Loom-Shuttles, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings representing like parts.

This invention relates to filling-carriers for loom-shuttles, such as are used in looms provided with automatic filling replenishing means, and in certain types of looms of this general automatic class the feeler which intermittingly feels the quantity of filling in the shuttle is arranged to operate upon the exposure of a metallic contact member, usually a band or ferrule mounted upon the filling-carrier. Such contact member is covered by the filling until the latter has been exhausted to a predetermined extent, the contact member being made of magnetizable or electroconductive material, depending upon the employment of magnetic or electrical devices to control the operation of the fillingreplenishing mechanism.

My present invention has for its object the production of a filling-carrier provided with a metallic contact member or band of such construction that it will not become loose by the shrinking or swelling of the filling-carllel.

Figure l is a top or plan view of a portion of the lay and breast-beam of a 100m, showing a shuttle-feeler, and the shuttle is shown as provided with a filling-carrier embodying one form of my invention. Fig. 2 is a side elevation, enlarged, of a filling-carrier embodying my invention. Fig. 3 is a similar view of a modification thereof, the body of the fills-carrier being broken off; and Fig. at is a 7 like view of yet another modification to be described.

Referring to Fig. 1, the lay 4:,having a shuttle-box 6, provided in its front wall with an aperture 60, the shuttle'A, having an opening 61 in one of its sidewalls, the filling-carrier a, and the filling-feeler 30, adapted to enter the shuttle when the opening 61 comes opposite the aperture 60 in the front of the shuttle-box,may be and are substantially as in United States Patent No. 665,559, dated January 8, 1901, the filling-changing mechanism being omitted herein as forming no part of my invention. In said patent an annular continuous metallic band is mounted upon the body of the filling-carrier near its head to contact with the feeler 30 when the filling has been drawn ot'f sufficiently to expose the contact member, it or the feeler being magnetized and the other of the two parts being magnetizable. The filling-carriers are very generally made of wood and are subjected to various conditions of heat and moisture, so that with a continuous band the shrinking and swelling will soon loosen the metal band and it will drop ofi or become misplaced on the body of the filling-carrier. In order to obviate this defect and to provide for a firm and permanent attachment of the contact member to the filling-carrier, I make such member as a contractile metallic band, its normal internal diameter being slightly less than the external diamater of the part of the filling-carrier to which it is applied.

In Fig. 2 I have shown the contact member as an annular metallic band or ferrule d, split from end to end at d, the resiliency of the material and its normal internal diameter causing it to tightly clasp or embrace the body a of the filling-carrier near its head a, and preferably the split is made diagonal to prevent any possibility of the feeler entering between the edges thereof. Obviously if the filling-carrier swells the contact member will expand therewith and shrinkage of the filling-carrier will be accompanied by contraction of the contact member, so that it will follow up and closely grip the carrier, due to the resiliency of the metal. As the normal internal diameter of the band or ferrule d is less than the normal diameter of the part of the filling-carrier to which it is applied, it naturally follows that the band must be ex- 5 panded when it is applied, so that it tightly hugs the supporting part of the filling-carrier.

In Fig. 3 I have shown the contact member 6 provided with an irregular split to form a tongue 6' on one edge, which enters a recess or notch e in the other edge,presenting an irregu- Patent, is

l. A filling-carrier for loom-shuttles, and an elongated, split ferrule or band of resilient magnetizable material mounted thereupon, the opposed separated edges of the ferrule being arranged to prevent the formation of a continuous axial opening from one to the other end of the ferrule.

2. A filling-carrier for 1oom-shuttles, having a head and a body, and an annular elongated contact member mounted upon the body adjacent the head and split from one to the other end, the opposed edges beingirregularly shaped to prevent the formation of a continuous opening from end to end of the ferrule.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
